Recently stepped up to a provari mini and an ibtanked cartotank. Filled up my carto according to instructions I found here from Baditude and put the carto in my tank. I let it sit for a couple hours before using it also. Its been a couple days and not much vaping from it (light vaper) and I noticed this morning that the juice is starting to turn brown inside the tank.
What would cause this? Is it normal?
